elisp: Minibuffers

 
 19 Minibuffers
 **************
 
 A “minibuffer” is a special buffer that Emacs commands use to read
 arguments more complicated than the single numeric prefix argument.
 These arguments include file names, buffer names, and command names (as
 in ‘M-x’).  The minibuffer is displayed on the bottom line of the frame,
 in the same place as the echo area (The Echo Area), but only
 while it is in use for reading an argument.
